I have 11m and 13m Edge 2012, my crappy elbow can handle the bar pressure on the 11m, but I know that on the 13m I would not be able to do more than 2 days riding 3-4 hours each day before the tendonitis come back.

Anyway, any comparison on the bar pressure 2012 vs 2013 Edge would be apreciated.

Make sure you are on the back setting on the kite.
Qpro lines help alot too imo - zero stretch so you get much better input to the kite with less effort at the bar. I have 11/13 2012 and will pick up 13 2013 this week so I will let you know if I notice any difference.

Tried my 17 out today
Compared to the 2012 the 2013 def feel lighter and it does actually turn quicker, a pleasant surprise.
I laid them on top of each other and the wing tips are a bit wider on the 2013 17m

I have both the 2012 and 2013 Edge (11M, 13M, 15M) and there is absolutely no difference between last year and this year's Edge as far as bar pressure. Check your setting on the kite if you feel the bar pressure is too much. I'm a little surprised you are saying you have an issue with the bar pressure on your 2012. If anything my only complaint with the Edge is I can't make the bar pressure even more. The factory settings are as resistant as hot butter.

I had 2012 11m & 15m. Now I have 7m, 9m, 11m and 15m 2013 and the bar pressure feels about the same. On 11 and 15 back lines are set to the quick setting, on the 7 and 9 I keep changing between middle and quick setting.
I didnt notice any difference on the bar pressure between 2012 and 2013. The kites are different in any other aspect( better all around )
